1. Open the Render Global Settings window and choose Mental Ray in the Render Using drop-down list. In the Common tab, enter name of your file. In the Frame/Animation Ext drop-down list, select name.#.ext, and set the image format to Targa (tga) or .tiff .

2. Change Frame Padding to 4 to add 4 digits after the name. This setting keeps the animation's still frames in sequential numbers. In the Resolution section, select a Preset from drop-down list.


Hope that helps out!
